OBJECTIVE:To analyze the utilization and variation tendency of oral hypoglycemic agents in Wuhan area,and to provide reference for drug selection and enterprise production and sale. METHODS:The utilization of oral hypoglycemic agents in 34 hospitals from Wuhan area during 2011-2013 was analyzed statistically in respects of consumption sum,DDDs and DDC etc. RESULTS:The consumption sum and DDDs of oral hypoglycemic agents increased by 20% and 7% respectively year by year. Acarbose had a market share of over 40%. The drug use frequency of metformin ranked the second place only to acarbose. DPP-4 inhibitor had a promising future,with a consumption sum proportion of more than 10%,while the market share of traditional Chi-nese medicine had fallen below 3%. Except for repaglinide,gliclazide,glimepiride,Xiaoke pills,etc.,the selling of other medica-tions are consistent with the user. CONCLUSIONS:The utilization of oral hypoglycemic drugs is basically rational in 34 hospitals from Wuhan area during 2011-2013.

Objective To investigate the effect and safety of different PaO2 to the reoxygenation injury of cyanotic congenital heart disease through controlling the FiO2 when initiating cardiopulmonary bypass (CPB).Methods Thirty patients with cyanotic congenital heart disease were divided into 3 equal groups according the PaO2 when initiating cardiopulmonary bypass:group 1 (G1,PaO2 ＜ 120 mm Hg) ; group 2 (G2,PaO2 120-180 mm Hg),group 3 (G3,PaO2 180-250 mm Hg),and ten patients with acyanotic congenital heart disease were group 4 (G4,PaO2 ＞ 200 mm Hg).Serum CK-MB,cTnI,IL-6,TNF-α,SOD,8-ISO and S100β were measured before CPB、5 minute after CPB,10 minute after CPB,5 minute after cross clamp releasing,2 hours and 24 hours post operation with intemal jugular vein blood samples.Clinical results were also recorded.Results CK-MB,cTnI,IL-6,TNF-α,8-ISO and S100β3 were all normal without significant differences between them before CPB.After initiation of CPB,their levels in all groups increased,reached the peak before or after the stop of CPB,then gradually declined.At each time point,the levels of these indexes were G3 ＞ G2 ＞ G1 ＞ G4 with significant difference between them (P ＜ 0.05) ; The serum SOD levels of G4 were higher than the other three groups with significant difference(P ＜ 0.05).They all declined after initiation of CPB,reached lowest after cross clamp releasing,then gradually increased.At 5 minute after CPB,10 minute after CPB,5 minute after cross clamp releasing,2 hours post operation,there were significant differences between four groups (P ＜ 0.05),and at 24 hours post operation,the SOD levels of G4 were higher than the other three groups with significant difference (P ＜ 0.05).There were no significant difference between G1,G2 and G3 in SvO2,Lac,positive vasoactive drugs、ventilation time and ICU time.All patients were alive.Conclusion Low reoxygenation concentration can reduce the reoxygenation injury of cyanotic congenital heart disease,though there may be some potential influence to cerebral oxygen metabolism.Further studies about oxygen supplymethodsare necessary in deep hypothermia and long-time CPB.

Cardiovascular disease is a severe threat to human health and life. Among many risk factors of cardiovascular disease, genetic or gene-based ones are drawing more and more attention in recent years. Accumulated evidence has demonstrated that the loss or mutation of ataxia telangiectasia mutated (ATM) gene can result in DNA damage repair dysfunctions, telomere shortening, decreased antioxidant capacity, insulin resistance, increased lipid levels, etc., and thus can promote the occurrence of cardiovascular risk factors, such as aging, atherosclerosis and metabolic syndrome. In this review, we discusses the possible mechanisms between ATM gene and cardiovascular risk factors, which could be helpful to the related research and clinical application.

BACKGROUND:PA6 cells are bone marrow stromal stem cells from the mouse skul , and scientists have found that PA6 cells co-cultured with some kinds of stem cells have shown neural differentiation, based on which, PA6 cells can be used for repair of nerve injury. Therefore, researchers give more and more attentions to PA6, but few studies have addressed isolation and culture methods of bone marrow stromal stem cells from the skul . OBJECTIVE:To isolate and culture bone marrow stromal stem cells from the skul of Sprague-Dawley rats and to observe cellular morpholopy in vitro and perform immunofluorescence identification. METHODS:Under sterile conditions, newborn Sprague-Dawley rat’s skul was cut into pieces. Smal skul pieces were washed using Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. Single cellsuspension was made, and placed in culture flask. The culture medium was changed many times for cellpurification. The second passage of cells was obtained for morphology observation under an inverted microscope. cellsurface markers were detected by using immunofluorescence staining. RESULTS AND CONCLUSION:After the primary culture for 24 hours, cells exhibited adherent growth;after 3 days, cells were increased in number, and presented with irregular shapes, such as polygon, triangle, spindle and flat shape. After passage, cells were uniform in morphology, arranged in radial and bunch patterns, and exhibited strong adherent ability. Some cells grew in cluster, and proliferated faster than primary cells. Immunofluorescence staining showed that cells were positive for CD105, CD73, CD44, CD90, but negative for CD45, D34,CD14, HLA-DR. Results indicate that this method can obtain bone marrow stromal stem cells.

Objective:To comprehend morphology changes of temporomandibular joint in adults with mandible deviation,and the correlation in these changes.Methods:The mesofault radiographs of temporomandibular joint were taken in 21 adult patients with mandible deviation.The data described morphology of temporomandibular joint were analysed.Results:In adult patients with mandible deviation,the condyle process of opposite side was anterior and inferior when compared with deflected side.The height of condyle process,the upper height of condyle process,the gradient of prosobevel of condyle process and the gradient of back bevel of glenoid fossa were augmented when compared to deflected side.The gradient of prosobevel of condyle process showed positive correlation to the prosoblank of joint and the deep of glenoid fossa,and the height of condyle process showed positive correlation to the upper height of condyle process in both sides.The gradient of back bevel of condyle process showed positive correlation to the gradient of back bevel of glenoid fossa in deflected side.The gradient of back bevel of condyle process showed negative correlation to the supper blank of joint and the height of articular tubercle in opposite side.Conclusion:There are some differences in morphology of both temporomandibular joint in adults with mandible deviation,and there is some correlation between these changes.

The polymorphisms of the TPOX locus in two population were studied by PCR technique followed by the denatured PAGE and silver staining.Seven alleles were detected in each population of 100 unrelated Northern Chinese Han individuals and 93 unrelated African(Xhosa)individuals in South Africa respectively.No deviation from the Hardy Weinberg equilibrium was demonstrated.The power of discrimination(DP)and the exclusion probability(EPP)were 0 7978 and 0 4625;0 9141 and 0 6125 respectively.Comparison of gene frequency distribution showed that there is significant difference between different races.In addition,three rare genes were detected in we Africans(Xhosa)individuals.Sequencing proved that the only difference among them was the number of repeat unit in the region amplified by the specific primer pair.It might be due to the unequal exchange between chromosomes which was resulting in the production of a chimera.Our study showed that the TPOX locus has a high discriminating power which is important for the study of forensic medicine and human genetics\;

Objective To study the genetic polymorphisms of DYF155S1 locus in 107 unrelated individuals both in the Han population, China and the Japanese population. Methods MVR-PCR, automated fluorescence detection and DNA sequence analysis were carried out for studying. Results Five types of repeat unit and one type newly named type 6 which was resulted from the T22A substitution on Type 1 were detected. Type 6 is monopolized by Japanese and may be regarded as a racial characteristic genetic marker. The common arrangement of the repeat units was 3134 which were detected at 73.44 % and 67.44 % in the Han and Japanese populations respectively. The abundance of arrangement of 3134 is the character of yellow race. Next to the arrangement of 3134 was the arrangement of 134 which was detected at 17.19% in the Han population while the arrangement of 6134 was detected at 16.28% in the Japanese population. The average number of type 4 unit at the 3'terminal was 8.8 in the Japanese population much lower than 12.5 in the Han population. Conclusion This study implies that DYF155S1 locus is an important geneticmarker with good genetic polymorphisms. The population difference between the Han and the Janpanes is significant.
